GeForce RTX 2080 vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare all that to the Radeon RX 5700 XT 50th Anniversary Edition, which uses a 7 nm design. AMD has set the core frequency at 1680 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this particular card. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080		215 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 20 Watts (9%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce RTX 2080 is a small bit (more or less 4%) faster with regards to anisotropic filtering than the Radeon RX 5700 XT 50th Anniversary Edition. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
	Difference: 9960 (4%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition is a little bit (approximately 11%) better at full screen anti-aliasing than the GeForce RTX 2080, and also capable of handling higher screen resolutions better. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 10560 (11%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
